Application filed April 3, 1924; Serial No. 704,073.

This invention relates to machines for operating on parts of boots and shoes, fOr example, heels, heel lifts and heel bases, and particularly to positioning devices for locating a shoe part with respect to an operating tool, for example, a heel or heel part, with respect to a breasting knife.

' For the purpose of exemplification the embodiment of the invention selected for illustration is shown as incorporated in a machine of the type disclosed in United States Letters Patents Nos. 1,455,79-i and 1,475,795, granted November 27, 1923, on applications of Louis A. Casgrain, It is to be understood, however, that the invention is not limited in its application to machines of this type but that its novel features maybe utilized in other machines for feeding and positioning shoe parts with respect to an operat ng means.

Features of the invention consist inan organization comprising-an operating means and means for feeding a blank toward the operating means, with means engaging the blank and movable with the blank for alining the blank with respect to the direction of feed of the blank ororienting it with respect to the plane of operation of the operating means, As sh wn herein, the lowermost heel in a heel magazine rests upon a feed 7 table. and a feed slide engages the lowermost heel and moves it into position beneath a breasting means, for example, a reciprocating knife To insure that the longitudinal median plane of the heel. will bepresented in proper anguiar relation to the plane of action of the knife the forward or breast of the heel is engaged at opposite ends of its breast face during itsp'assage toward the knife by means movable with and by the heel, which means positions the heel with respect to the plane of action of Since the positioning means engages the forward end of the heel, it is moved with the heel into position beneath the knife and must be removed from suchposition duroperation of the knife. Novel mechanism is provided for releasing the positioning means-from engagement withthe heel and for; moving it out the way of the knife.

end a the knife. Y

of the positioning means;

The positioning neans may comprise, as

I shown, fingers having inturned ends'normally held toward each other and connected for equal and opposite movement. "The heel, as it is fed, separates the fingers by its passage between them and engages, by its breast end,

the hooked or inturned ends on the fingers.

The fingers are yieldingly held towardeach other and against movement with the heel preferably b the same spring so'that they move bodily with the heel and the feeding means while maintaining pressure on the breast and sides of the heel to hold the heel against the feeding means during the feed ing movement thereof and to position the heel in predetermined. relation to the direction of feed and to the plane of action of the knife. The'means for removing the fingers from engagement with the heel is shown as independent of the means for moving the fingers out of the path of the knife 'mined and is arranged to effect'apredet separation of thefingers to release their inturned ends from the heel irrespectively of the amount of separation of the fingers determined by the heel between them. Separation of the fingers to free them from engagement with the breast of the allows the spring against which they are moved by the heel to react and draw them back from their position under the knife. To insure against failure of the spring so to act, how-' ever, additional means is provided for positively retracting the fingers. As shown a cam on the knife slide acts on a lever having suitable lost motion connections to a side which car ice the fingers to retract the during the initial part of slide and ting as the knife movement. 7

These and other features of the invention will appear more fully from the following description when read in connection with the acconmanying drawings and will be pointed out in the appended claims. In the drawings, r V

Fig. 1 is a side elevation of the upper part of a machine embodying the invention;

Fig. 2 is a plan view, parts being removed and broken away to show" the construction and Fig. 3 is a planview illustrating the accrank and connecting rod tion of the feeding and positioning mechanism upon a heel.

The organization of the machine is, in general, similar to the disclosure of the pat ents above referred to, to which reference may be had for description of'parts not herein fully explained.

The machine comprises a column 2 in which a knife slide 4 carrying a knife 6 is mounted for vertical reciprocation. by a (not shown). A feed table 7 has attached to its inner end by screws 8 a wooden cutting block 9 (Fig. The block 9 is preferably arran ed with the end grain of the wood forming the cutting surface of the block. The table .7 has a T-groove 10 formed in its lower face which is engaged. by the head 11 of a bolt 12 by which the table is held to a supporting frame 14. At its inner end the frame 14 is supported in. a head 16 secured to the upper end of a fixed post 18. The frame 14 has circularly curved tongues 20, 20' which engage corresponding grooves in the head 16, the

' axis of curvature of the tongues being locatcd in the surface of the cutting block 9 so that thetable 7 and the frame 14 may be adjusted about said axis to vary the angular relation of the tread face of the heel on the table to the plane of action of the knife 6. The adjustment is maintained by a bolt 22 passing through a slot 24 and threaded into a downwardly projecting portion of the frame 14. A pointer 26 has its upper end connected to the head 16 for rocking movement about the same center as the frame 14 and has its lower end connected to the bolt so that it moves with the frame 14 and in dicatcs the adjustment thereof relatively to the head 16.

A bracket 28 on the frame 14 (shown partly broken away) supports a magazine comprising a plate 30 to be engaged by the breast end of the heels, the plate being adjustable vertically by a screw 32 against a collar on which the plateis held by a spring 34. The magazine has two side plates 86 which are adjusted toward and from each other by a right and left screw 38 geared to a handwheel 40 which is supported on the bracket 28. A'pair of U-shaped members 42 engage the curved ends of the heels to hold thcn'r in the magazine.

A feed slide 46 1s provided with tongues which engage grooves 47 formed in the edge faces of the table 7 and is connected by links 48, 48 to the ends of arms 50, 50 of a (shaped lever 51 pivoted at 52 to a bracket supported on the post 18. The lever 51 is operated, by mechanism fully described in the before-mentioned patents to cause'the slide 46 to move to'the right (Fig. 1) far enough to allow the lowermost heel in the magazine to drop in front of it and then to move in the opposite direction to push the weaves 'tioned patents, to give the slide a slight-forward movement after the first cut is made to position the heel for a second or finishing out upon a second operation'of the knife. The feed slide 46 has a V-shaped notch (Fig. 3) for engagement with the rounded end of tl e heel which is being fed, the notch acting laterally to locate the end of engaged by it.

To maintain a downward pressure of the heel while it is being fed, one end of a plate 56 is pivoted at 57 to the plate 32 of the magazine and has its other end loosely connected to a frictionally operated rod 58. On the lower side of the plate 56 is secured a leaf spring 60 which bears on the heel during starts downwardly the rod 58 is moved by the heel frictional connection therewith to force the plate 56 upon the heel and hold it for the breasting operation.

The rod 58 is straight and exends longitudinally through a threaded for verticaladjustment, such adjustment being maintained by a set nut 63 on its upper end. The bar 62 is frictionally held at 64 in a projecting portion of the knife slide 4 and near its lower end has a recess 65 in its inner face to receive astationary projection 66 secured to a bracket 68 bolted to the machine frame. The rod 58 passes loosely through a hole in the projection 66'and the projection, by engaging the upper and lower walls of the recess 65, limits the movement imparted to the bar by the knife slide through the friction means 64. The plate 56 therefore, by proper adjustment of the rod58, is caused to clamp the heel early in the downward movement of the knife and to release it upon the upward movement of the knife.

In order that the heel may be presented with its longitudinal median plane in proper bar-62 in which it is relation (usually normal) to the plane of- I action of the knife, s'des and breast corners of the heel during the feeding movement of the heel'is pro vided. A slide 70 (Fig. 2) has on its upper face a T-guide 72 which engages the T-slot 1.0 in the lower face of the table 7. The slide 70 therefore can move in the directionof movement of the feed slide 46. Pivoted on the slide 7 0 are two fingers 74, .75 having int-urned ends forming stops which engage op-' posite ends of the breast face of the heel as it is fed. The fingers 74, 7 5 have vertical pivot portions 76, 78 mounted to turn in the slide 70. ()peratively connected to the pivot" 7 6 of the finger 74 is an arm 80, and secured to the pivot 78 of the finger is an arm-"82. The arms 80, 82 extend toward each other means engaging the 'are separated, that is,

and are geared together so that movement of one finger will move the other equally and. oppositely. Connected between thearm 82 and the frame 14 is a tensionspring 84 which not only tends to move the fingers toward each other but tends also to move the slide 70, on which the fingers are 'car-. ri'ed, away from the knife, holding it normally against a stop .85 on the frame 14. The connection of the finger 74 to the arm is as follows: The arm 801s loose on the pivot 76. Fixed to the pivot 76 is a beveltoo'thed segment 88' having an arm 90 in which is threaded a screw 92 that engages a projection 94011 the arm 80. The screw 92 provdes for adjustment of the finger 74 relatively to its ar1n.80 to control the lateral position of the heel between the tingers and causes it to be presented centrally of the knife. The segment 88 also arm 96 whichlimits closing movement of the fingers by engagement with a screw 97 threaded in the slide 70. *By adjusting the screw 97 the separation of the fingers when no heel is between them may be controlled.

For opening the fingers to release them from the heel a bevel-toothed pinion 98 meshing with the pinion 88 is fixed to a horizontal rock-shaft 100 j'ournaled in a bracket 102 depending from the slide 70.

At, the outer end of the rock-shaft "100 is fixed a ratchet segment'104 with which a multiple pawl 106 cooperates. The pawl 106 is shown as in three parts,the teeth being differentially arranged to pick up the ratchet segment 104 in substantially any position of its teeth with respect to the pawl. The three parts of the pawl 106 are each held toward the segment. 104 by a separate spring 105,

' one end of each spring bearing on a part of the pawl and being fixed 'on its other end to a clamp 110 carried by a sliding block 112.

The pawl 106 is pivoted at 114 to a pawl lever 116 which is fulcrumed at 118 on the block 112, a torsion spring 119 being arranged about the pivot 118 of the lever 116 to swing the lever in a clockwise .direction to holdthe pawl 106 depressed. The block 112 is arranged to slide on aguide 120 formed on the frame 14 and is normally held by a spring 122 against a stop pin 124 on the frame 14. A pin 126 on the slide block 112 limits movement of the pawl 106 toward the segment 104 when the pawl and segment when the slide 70 is against its stop 85.

The mechanism has now been sufficiently described to enable the operation of'this and the remaining mechanism to be readily understood. As shown in Fig. 1, the knife slide 4 is making its upward stroke, The feed "slide has been moved to the right to receive a heel from the magazine and has pushed the heel toward the knife '6 under the has an beneath the knife.

' clamp leaf spriilgBO and between thefingers 74, 75 which were held toward each other by the spring 84 and were separated by the heel against the spring. The lateral positionof the breast end of the heel has been deter mined by pressure of the fingers on the sides of the heel near its breast, end. The breast end of the heel has engaged the inturned ends of the fingers and the heel has hadits longitudinal median plane AB (Fig. 3) oriented with respect to the plane of action C-D of the knife, the rear end of having been shifted if necessary in the notch of the feed-slide 46.v The slide {70 of course was held against the stop 85 by the spring' 84 with-the segment 104 out of reach of the pawl during the separation of the fingers by introduction of the heel and the pressing of the heel against the inturned.

irrespectively of the width of the heel.

the upwardmovement of the slide continues, Y

the feed slide will continue to push the heel toward the knife, and the slide 70 will engage the slide 112 and move it against the tension of the spring 122, the cooperative relation between thepawl 106 and the segment 104 being undisturbed. Finally, the movement of the feed slide will position the breast end of the heel and the fingers 74, 7 5 YVhen theknife slide reachesits'upper limit, movement of the feed slide will stop, and'upon reverse downward movement of the knife slide the friction rod 58 will force the plate 56against the heel to hold it in position, and before the knife reaches the heel an arm 128 fixed to the knife slide will engage the pawl lever 116 and operate it to lift the pawl 106 and turn the segment 104 in a clockwise direc tion. This acts through the bevel-toothed segments 98, 88 to open the fingers 74, 75 and release them from the heel. The spring 84can then react to draw back the slide 7 0 loo llU

This mechanism causes the slide 70 and the lingers '74:, 75 to be positively withdrawn in case of failure of the spring 84"t-o withdraw them. A lost motion connection at 142 between the link 1334 and the lever 130 permits the spring 84 to withdraw thelingers and slide without moving a shoe blank,

the lever 130; the spring therefore can act more quickly to retract the'iingers since 1t does not have to overcome the inertia of the 1 lever 1'30.
